Is my employer breaking labor laws, including defamation of character?

I work in a preschool as a teacher's assistant and was recently accused (falsely) of child abuse by the administration at the school I work at. They based this accusation off of two people's accusations, and when I came to read these peoples' statements, I found out that there was no accusation of child abuse included. Specifically, my bosses told me that I was accused of hitting a child, but the people who complained about me included no such accusation. The school sent the grievance to the DCF, and it was weeded out because it was obvious that there was no cause to think I had abused a child. This situation has greatly distressed me to the point where I cannot go into work because of my anxiety, and I am looking for legal recourse.
